How to Add a Link and QR Code to Your Email Signature: Turn Every Message into a Small Ad

If you send dozens of emails a day, each one carries the small space under your signature. That space is often filled only with a name, title and phone number. Yet a single well-chosen link can become a steady source of traffic.

What should you add to the signature?

• One main link: your website, booking page, portfolio or most important campaign.
• A short call to action: "See our services", "Book a slot".
• If you like, a small QR code; handy for people who read on a desktop but want to scan with a phone.

Why a short link?

Long addresses look messy in a signature and can break lines in some email clients. A short link looks neat and lets you see the click count. If you create a separate short address for your signature link, you can separate the interest from this channel from others.

How do you set up a good signature?

• Keep it short: a name, title, one way to reach you and one link are enough.
• Put the text link ahead of images; some clients block images by default.
• Print or add the QR code large enough, but avoid images that take up space in the signature.
• Test on mobile too: the signature should not overflow on a phone.

Common mistakes

• Adding several links: attention is split and clicks drop.
• Leaving an outdated campaign link in the signature.
• Spreading the link without testing it: a typo repeats across thousands of messages.
• Using a very large image: it weighs the email down and increases the risk of hitting a spam filter.

Measure the results

After a month, look at the click count of the link in your signature. If your team uses the same signature, you can create a separate short link for each person and see whose emails bring more clicks.
